The request was rejected because no multipart boundary was found in springboot
The problem is that you are setting the Content-Type by yourself, let it be blank. Google Chrome will do it for you. The multipart Content-Type needs to know the file boundary, and when you remove the Content-Type, Postman will do it automagically for you.
Unchecked the content type in Postman and postman automatically detect the content type based on your input in the run time.
